Grease and flour three 8-inch round baking pans. Or alternately, you can use two 9-inch round baking pans. (Just be sure that every square inch of the pans greased and coated in flour so that the cake does not stick!)

In the bowl of a large stand mixer, mix together oil, granulated sugar, and brown sugar until combined and smooth. Add in the eggs one at a time, then the vanilla, and mix until smooth.
